Because most people care very much about social relationships, and like it or not, other people just naturally tend to be put off by things that look strange or unattractive. You might decide you genuinely don't care what anyone thinks of you, but realistically speaking that's a somewhat unusual stance.
I get that, but the way people talked about it, I though it was something really horrible. And it turns out it is just a little different. I have used some way more strange stuff in this life of mine.
